analyze_spectrum

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations are absent, and the description only states 'FFT spectrum analysis' without disclosing behavioral traits such as whether it is read-only, latency expectations, or potential side effects. The agent must infer that it is a read operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise (three words) with no unnecessary information. Every word is meaningful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given zero parameters and no output schema, the description is minimally sufficient but lacks details about the output format (e.g., frequency bins, amplitude values). Among many sibling analysis tools, more context would be beneficial.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has zero parameters with 100% schema description coverage (empty schema). With no parameters, the description does not need to add parametric detail. Baseline 4 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'FFT spectrum analysis' uses a specific verb ('analyze') and resource ('spectrum') with a clear method ('FFT'). It distinguishes from siblings like 'analyze' (generic) and 'analyze_rhythm' (rhythm-focused).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like 'analyze', 'analyze_rhythm', or 'detect_key'. The description does not mention prerequisites, context, or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
